Kind of. But not really a bug. It's just a message that shows up every time you starting the app as a non-root user. The message itself was introduced long time ago, but it wasn't printed for unclear reasons. It's probably some change in logging subsystem uncovered it. I just checked and found that message appears starting from v18.02. But OVS stuck with 17.11 LTS where this message exists, but not printed for some reason. That's why this wasn't an issue previously. P.S. OVS tests just checks the output for error messages. Tests themselves works fine. They are not actually using DPDK.
